It remains an independent, non-chain facility, which contributes to its unique and unpolished presentation.
Katsurahama Aquarium is a privately operated, small-scale facility located directly on the sandy shores of Katsurahama Beach. Unlike modern, sprawling complexes, this aquarium emphasizes intimate, hands-on encounters with animals rather than massive tank displays. The collection features regional Japanese river fish alongside various marine species and penguins. Staff-led animal interactions are a core part of the visitor experience. The facility has been in operation since 1931, maintaining a retro, nostalgic atmosphere. It is integrated into the larger Katsurahama park area, providing visitors with immediate access to the coastline of the Urado Bay entrance. The aquarium serves as both a tourist destination and a center for marine biology education in Kōchi Prefecture.
